LIQUID-DISPENSING APPARATUSu.

Application filed February 21, 1922. Serial No. 538,171.

T 0 all whom it may concern Be it known that I, EMORY CRoUsE, a citizen of the United States, residing at Wichita, county of Sedgwick, and State of Kansas, have invented certain new and useful Improvements in Liquid-Dispensing Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to liquid dispensing systems and has special reference to an apparatus adapted for use in' dispensing gasoline.

It is customary atpresent to elevate the gasoline into a' glass container graduated in gallons and to run the gasoline from the container into the fuel tank of the auto mobile through a hose. In my application Serial No. 529,773, filed January 16, 1922,

I have described and claimed a system and an apparatus for dispensing liquids, in which the liquid may be elevated into the dispensing tank by means of a suction pump, or by the employment of compressed air. There are many places where the compressed air lift is not desired and where the gasoline is pumped by hand or by power, and it is the object of this invention to produce a very simple dispensing system for use in such places.

In order to more clearly describe my invention, I shall have reference to the attached drawing in which Fig.- 1 is a view showing my dispensing system in assembled relation, parts thereof being shown in section or broken in order that the relationship of the parts may be better seen. 4

Fig. 2 is a detail on a larger scale showing the means for automatically operating the check valve in the overflowpipe, and connecting the same with the suction line Whden the measuring tank is overflowing; an

Fig. 3 is a detail showing the upper end of the supply pipe.

The same reference characters will be used to indicate the same parts throughout the several figures.

Numeral 1 represents the fioor or pavement of the filling station and 2 represents the gasoline reservoir which is located beneath the pavement in the manner shown. A fill pipe 3 extends through the pavement l and opens into the reservoir 2. The top of the fill pipe 3 has a removable cap 4, beneath which vent holes 5 are provided. A suction line 10, provided with a strainer 9, extends from a point near the bottom of the tank 2 to the dispensing apparatus, which I will now describe and which consists of a sheet metal housing which has a slight upward taper and is surmounted by a cast iron hood 12-, to the upper side of which is secured a glass bowl 13 of the desired capacity, usually five or ten gallons. Glass bowl 13 is provided at its top with a cast iron cover 14 which is connected to the bottom 15 of hood 12 by means of a pipe 16 having nuts 17 by means of which a clamping action may be secured. An ornamental ca 18 covers the top of the cover 14 and tiiis is in turn surmounted by a spherical glass globe 19 within which is located a lamp (not shown). Pipe 10 extends from the tank to a point beneath the dispensing apparatus from whence it extends vertically to a point near the top of the measuring bowl 1% The upper end of pi e 10 is provided with'a cap 20 beneath whic are a number of openings 21. -A cylindrical aluminum member '22 having its upper end closed as indicated by numeral 23, and rovided with an opening 24, surrounds t e upper end of pipe 10, as shown in Fig. 3. By the means just described, the gasoline will emerge from holes 21 and flow downwardly between pipe 10 and the inner side of tubular member 22 and enter the measuring bowl 13 near the bottom thereof. In order to transfer liquid from the reservoir to the measuring bowl 13, I provide the suction line 10 with a rotary pump 25, of the type described and claimed by me in my application Serial No. 502,- 323, filed September 22, 1921. Pump 25 may be operated by hand through the medium of a crank 26, or by power. In order to guard against danger from overflowing and to insure that the bowl 13 will always be filled to the desired level, I provide an overflow pipe 27 whose upper end is on the level of the surface of the liquid within the bowl when the latter is filled.- In order to its lowermost a check valve 28 which prevents liquid from flowing downwardly and into the suction pipe 10. The reason why check valve 28 is necessary is that without it the pump 25 would become inoperative as air would enter through pipe 27. and flow into suction pipe 10, instead of gasoline being raised from the reservoir 7. I also provide a check valve 29 in the suction line directly above the T 30; this valve acts as a foot valve and prevents the gasoline from running out of the pump 25. Valve 29 might be omitted, but in that case the gasoline would in most cases flow back into the reservoir when the pumpyvas idle, .and entail a considerable amount of extra labor whenever the bowl 13 was to be filled. It is evident that gasoline would not flow from pipe 27 into pipe 10 unless some means were provided for opening the check valve 28 when gasoline is overflowing into pipe 27, and in order to automatically open this valve when liquid enters the overflow pipe, I have provided the following means. Directly above valve 28 I provide a I 6 to the upper end of which is secured a short piece of pipe 7 which is connected to the bottom of a drum 8, within which is mounted a float 31 which in its lowermost position rests upon the tops of supporting brackets 32. A lever 33 is pivoted at 34,and is con-' nected by means of a rod or wire 35 to the plug part 36 of the valve 28. When lever 33 is moved upwardly plug 36 will be raised 'from its seat and the contents of pipe 27 will be permitted to flow downwardly and into pipe 10. 'Ihe outer end of lever 33 is connected by means of links 37 with a second lever '38 which is pivotally. mountedon a pintle 39 and has its free end connected to the bottom of float 31 by means of a flexible connection 40. When liquid overflows into pipe 27, it enters the drum 8 and raises the float 31 which in turn opens the valve 28 and permits the liquid to flow into pipe 10. If the pump 25 is operating, the liquid from the overflow pipe will he carried back into bowl 13, but if the pump is idle, it will return to the reservoir 2. When the overflow ceases, the float 31 will gradually fall to position and permit the valve 28 to close. a 4 1 In order to transfer the liquid from the bowl 13 to the fuel tank, I provide a hose 41 which is equipped at its nozzle extremity with an. automatically closed spring-operated valve 42, which is in communication at its. end opposite the nozzle, by means of pipes 43, with the bottom 15 of hood 12.

When it is desired to drain the measuring bowl withontemploying the hose all. as at night or at the close of business, I open valve 4A which controls the operation of pipe 45 which extends from the bottom of bowl 13 to pipe 27, to which it is connected by means of a T 46.

The dispensing apparatus described above is simple in .construction and requires one pipe line only from the underground reservoir to the dispensing stand. It can therefore be readily installed in places where other systems employing only one pipe have been used, thus obviating the necessity of cutting cement pavements and digging trenches, as would be necessary if an additional pipe would be required.
